Transient Ischemic Attack

What is transient ischemic attack?
A transient ischemic attack (TIA) happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away. With a stroke, the blood flow stays blocked, and the brain has permanent damage. Some people call a TIA a mini-stroke, because the symptoms are those of a stroke but don't last long.

A TIA is a warning: it means you are likely to have a stroke in the future. If you think you are having a TIA, call 911 or other emergency services right away. Early treatment can help prevent a stroke. If you think you have had a TIA but your symptoms have gone away, you still need to call your doctor right away.
